3 of us headed back in from fishing with a seriously confused 5-7' following sea.Passing last buoy to be inside the inlet and boat snaps HARD to port with a free spinning steering wheel. Jump on the throttles but can't get the vessel to respond correctly due to rudders stuck hard starboard. Drifted back out the inlet to try to get in a better position to determine best plan. Determined she would respond better in reverse then fwd so that's what I did. It took over an hour to navigate back in where tow boat brought us back to our slip. The steering ram has apparently been rubbing on a hose that wasn't visible and it finally ruptured. I noted there are several feet of heavily rusted hard lines that I want to replace. I forgot to grab my manual, can someone identify this apparatus the lines run into?
